ROLDIN 'S. ROBBINS AND ALPHONZO H. BROAD, OF BERKELEY, CALIFORNIA.

WALL-PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 402,857, dated May '7, 1889.

Application filed July 26, 1888- Serial No. 281,100. (No model.)

To all whom it may concern:

Be it known that we, ROLDIN S. ROBBINS and ALPHONZO H. BROAD, both of Berkeley, in the county of Alameda and State of California, have invented a new and Improved Wall-Protector, of which the following is a full, clear, and exact description.

The object of the invention is to provide a wall-protector of cheap and durable construction, adapted to be secured to the backs of chairs, sofas, and other articles of furniture.

The invention consists of a combined baseplate and roller-supporting arms formed integral from a blank cast or stamped as hereinafter described; and the invention also consists in the peculiar form of the blank, as will be hereinafter particularly described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of a wallprotector constructed in accordance with our invention, and Fig. 2 is a plan View of the blank from which the base-plate and rollersupporting arms are formed. 1

The blank A, Fig. .2, of suitable metal, is formed with two opposing U-shaped or approximately U-shaped slots, at a, the center, a, of the blank between the said slots being solid. Thus the U-shaped slots at a divide the blank into an inner member, B, and an outer member, 0, the solid central portion, a, of the blank uniting the said members.

The inner member, B, is left flat to form the base-plate, as in Fig. 1, and in its ends are formed holes I) b, for receiving screws or equivalent means of securing it to the back of a sofa or other article of furniture. The

ends of the outer member, 0, are bent toward each other, so that their extreme outer ends,

0, lie in a plane at right angles to the baseplate B, or approximately so, the said ends thus being parallel with each other, whereby they form supporting-arms for a globular roller, D, of rubber or other suitable material, the journals d of the roller having their bearings and rotating in holes a of the supporting-arms.

The blanks may be stamped or cast, as desired. In either case they may be quickly and cheaply produced and the protector formed at a low cost, and it is evident it forms a durable article of this character. The protector is adapted for use upon either a vertical or inclined surface, in each case conforming to the line of the Wall, owing to the globular shape of the roller.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture, a wall-protector consisting of the globe-shaped roller D, provided with the journals d, and a bracket formed of a base-plate, B, provided with apertures 19 in its ends, and the approximately-semicircular arms 0, projecting from and integral with the base and provided with apertures c in their extreme outer ends, 0, for the reception of the journals of the roller, as set forth.

2. The blank for forming Wall-protector brackets, consisting, essentially, of a metal plate formed with opposite U-shaped slots dividing the blank into inner and outer members united at the center of the blank, the said inner and outer members being aper= tuged, substantially as shown and described.
